As per the MediaWiki version lifecycle[1], I would like to announce the formal end of life (EOL) of MediaWiki 1.38 as of today, Friday June 28, 2024.

1.40.4 is expected to be the last release for this branch.

This means that MediaWiki 1.40 will no longer receive maintenance or security backports. It is therefore strongly discouraged that you continue to use it.

It is recommended to upgrade either to MediaWiki 1.41, which will be supported until December 2024, or 1.42, which will be supported until June 2025.

Thanks!
